ROTARY PLow.

SPECIFICATION forming part of Letters Patent No. 291,127, dated January1, 1884.

- Application filed-May 16, [883. (N0 model.)

To aZZ whom it may concern Be it known that I, JOHN AUsTIN, of Chicago,in the county of Cook and State of Illinois, have invented certain newand useful Improvements in Rotary Plows, of which the following, inconnection with the accompanying drawings, is a specification.

In the drawings, Figure 1 is atop or plan view of a rotary plow providedwith my improvements. Fig. 2 is a side elevation of the same. Fig. 3 isa horizontal section in detail, representing the construction of thedisk-hub and its relation to the disk axle or spindle. Fig. 4 is a sideView of the flexible washer. Fig. 5 is a rear view of a part of theframe, showing the connection therewith of the tilting draft-wheels andthe means employed for tilting them. Fig. 6 is a side view of one of thesides of the rotary disks, partly broken away to more fully show theconstruction of the same. Fig. 7 is a side view of one of the flangesforming a part of a rotary-disk, and Fig. 8 is a section in the plane ofthe line as x of Fig. 6.

Like letters of reference indicate like parts.

My invention relates to that class of plows provided with rotary disksfor laying the furrows, and in which the said disksare set at an angleto the line of draft. In the example shown I have represented a sulkygang-plow -.of the class referred to.

A represents the frame of the plow.

B is the draft-tongue, which is attached to p the forward part of theframe A, and rigidly connected thereto by means of the braces a a.

O is the king-bolt. D is the drivers seat.

E is a crank-axle, arranged diagonally and turning. in suitable boxes orbearings applied to the frame A.

FF are rotary disks, one of which is ap* plied to the spindle of theaxle E.

G is the hub ofthe disk F, and G is a concavo-convex flange extendinglaterally from the rear endof the hub G, and cast or made in one and thesame piece therewith. This flange has a rim, 1), having a curvaturedifierent from that of the body of the flange, as is clearly indicatedin Fig. 1; and c c are pocket-s so or depressions setting back from theflange G,

as is clearly indicated in Figs. 6 and 7, and also in Fig. 8.

v H is an annular blade, made in sections, and bolted or otherwisesecurely fastened to the rim b. Theedges of these sections meet ornearly meet in the perimeter of the disk, but diverge from each otherfrom their outer eorners inward, as shown at (Z d, and the pockets ordepressions c 0 lie directly behind the spaces or openings between theradial edges of the sections of the disk H. These sections are somewhatdishing in form, as shown. The in terior of the inner end of the hub G'fits upon a collar-band, e, on the spindle of the axle E.

I is an annular piece of rubber stretched over the collar 0, and locatedbehind it. This annular piece I clamp to the flange G bymeans of a ringor annulus, J. I retain the disk F upon its spindle by means of a screw,K, passing freely through the outer end of the hub G and screwed intothe end of the spindle, as shown in Figs. 1, 2, and 3. I construct andapply the disk F the same as the disk F, excepting that it rotates upona fixed spindle rigidly applied to a supplemental frame hinged to themain frame, as will-hereinafter more fully appear.

L L are shears attached to arms rigidly applied to the frame, andarranged to shear against or with or nearly against the working-face ofthe sectional parts of the disks F and F.

M is an arm or lever rigidlyattached to and projecting forward from theaxle E, and N is a lever pivoted to the frame A. The lever N has twoarms or branches, f and f, and the latter is connected at its forwardend to the forward end of the arm or lever M by means of a link, 9.

O is a segmental arch rigidly attached to the frame A, and having in itthe holes or openings h h. I set the lever N in different positions, andlock it temporarilyby means of apinpass ing through it and into one oranother of the openings h h. By this means the axle E may be adjustedrotatively, with the result hereinafter referred to.

P is a lever, pivoted at 13 to an arm or support, Q, attached to theframe A. The forward end of the lever P is connected to the rear end ofthe arm f of the lever X by means of a link, j.

A is a supplemental frame hinged to a rear cross-bar, B, forming a partof the frame A, and C is a spindle rigidly attached to the frame A. Thedisk F is mounted upon the spindle O in like manner as the disk F ismounted on the spindle G, but is located to turn a furrow adjacent tothat turned by the disk F, as is clearly indicated in Fig. 1.

It is an upright rigidly attached to theframe A. The rear end of thelever P is connected to the upright 11 by means of a link, S. By thismeans the frame A, and hence the disk F, may be set either higher orlower by adjusting the lever end for that purpose, and both disks F andF will thus be either raised or lowered simultaneously.

T T are the draft-wheels, and D D are independent axles upon which thesaid wheels are mounted.

E is a segmental arch applied to or forming a part of the bar B, and k7; are holes in the said arch.

F is a T-levcr, pivoted to the bar B at the junction of its vertical andhorizontal arm.

H H are links connecting the inner ends of the axles D D to the ends ofthe shorter or horizontal arm of the lever F. The lever F is capable ofbeing tilted or inclined laterally and locked temporarily by means of ayielding lever, F, pivoted thereto, and pro vided with a pin, Z, passingthrough it and entering one or the other of the holes k k removably. Imake the bar B, by preference, of two parts or parallel pieces boltedtogether, but far enough apart to allow the lever F, axles D D, andlinks H H to play or move between them as the lever F is adjusted. Ibolt or otherwise securely connect the support Q to the arch E.

In some respects the plow now described is similar in construction andoperation to plows of the same class heretofore constructed. Forexample, the plowing-disks are dishing and set in. planes diagonal tothe line of draft, and are also arranged so that one will lay a furrowin advance of the other, and are adjustable.

This invention relates, principally, to the construction of theplowing-disks and to the means employed for so inclining the draftwheelsas to resist the lateral presssure of the soil upon the disks, and alsofor regulating the depth of the furrows. To tilt the wheels T T, I movethe lever F in the direction i11- dicated by the arrow shown in Fig. 5,and lock it temporarily in the posit-ion so set, in the manner alreadydescribed. It will be perceived, on reference to the said figure, thatthe wheels T T will be inclined or so set as to resist the pressureexerted upon the plowing-disks, and hence cause the plow to travelproperlybehind a team, so as to lay the furrows in the directiondesired. It will also be perceived that the whole plow-frame andplowing-disks will be lowered in proportion to the inclination of thewheels T T, thus causing the furrows to be deep or shallow, as may bedesired. The deeper the furrows the greater will be the lateralpressure, under ordinary circumstances, and when the depth of the furrowis regulated by the depth of the wheels T T their inclination willcorrespond to that pressure; but, as will also be perceived, I have madeprovision, through theinstrumentality of the lever N and itsconnections, for adjusting the plowing-disks vertically independently ofthe means employed for inclining the wheelsT T. It will also be observedthat while one wheel T runs in the furrow and the other upon theunplowed ground, the frame will be supported horizontally, owing to thefact that in tilting the said wheels the outer end of the hub of thefurrow-wheel moves downward and the outer end of the hub of theland-wheel moves upward.

In constructing the disks F and F in the manner described, I aim toprevent them from becoming clogged, and also to shut out sand or gritfrom the spindles on which they turn, and in endeavoring to accomplishthese results I have also aimed to employ such fea tures of constructionas would render the making of the disks comparatively cheap. It will beperceived that the fine or broken soil which otherwise might remain uponthe working-faces of the disks will pass through the spaces (1 (1 intothe pockets 0 c, and thence fall out at the back of the disks as thelatter are rotated. By making the hub G-andflange G in one and the samepiece, the ends of the hubs and the screws K K covering the ends of thespindles, as shown, the grit and dirt are prevented from there passingin between the hubs and their spindles, and the flexible diaphragms orrings I I shut out the dust and grit from entering the opposite ends ofthe hubs.

I am aware of the construction shown and described in United StatesLetters Patent to A. J. Manny, K0. 50,018, wheel-cultivators, September19, 1865; J. \V. Surta, No. 112,394, March 7, 1871, gang-plows, and J.Nicewood, No. 257,603, May 9, 1882, sulky-plow, and I do not thereforehere intend to claim the same; but,

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, substantially as specified, with the frame of arotary plow having a diagonally-arranged plowing-disk. of thedraft-wheels T T, the vertically tilting sectional axles D D, carryingthe said wheels and pivoted to the said frame, and an adj usting-leverjointed to the said axles,for the purpose of thereby admitting of thesaid wheels being both inclined laterally in the same direction by meansof the same lever.

2. The combination of the wheels T T, the vertically-tilting axles D D,the barB, the

T-lever F, the links H H, and means for the blade H, made in sections,fastened to the 10 temporarily loekingthe said lever, in conrim of thesaid flange, the radial edges of the nection with the plow-frame,carrying diagsaid sections having between them spaces onally-arrangedrotary plowing-disks, subopening into the said pockets, substantially 5stantiaily as and for the purposes specified. as and for the purposesspecified.
